Beginning Wednesday May 5th we shall commence reconfiguration of the Accelerator Systems for the upcoming PEP run, as well as for an E157 run. This turn on shall present a series of complications above and beyond those seen previously. Complications include:

Setup of injector for three (or four) drastically differing interlaced

The goal shall be to have both e+/e- available for PEP injection as well as an E157 beam available in BSY as early as May 10th. We feel strongly that if we want to succeed at this goal, the initial setup emphasis should be placed upon the most difficult to establish beam, i.e. the E157 beam. We anticipate that this shall delay the availability of e+/e- to PEP compared to a setup absent of E157. In what follows (sort of a timeline, or "order of operations"), we adopt this strategy.

Turn on all magnet and RF systems required in these areas (as compatible with E155x), with configuration values from startup configs referenced below.

Complete cold and hot checks for each of these systems. Carefully document (CATER) problems which would interrupt ability to deliver beam to PEP/FFTB. Coordinate/prioritize repair activities with support groups (Power Conversion, Controls, etc.)

Continuously monitor these systems to identify faults that would interrupt a PEP or FFTB program.

Procedure for this is tricky. There shall be BNS damping for the E157 beam which the PEP beam shall not see. Need to "dial up" the BC8 phase ramp to put the BC8 electrons up upon the crest of the RF bucket (~20 degrees different than the E157 electrons), then compensate for the additional energy by lowering BC8 off of the crest of the SLED pulse. FJD needed for this?

Steer extraction/bypass as necessary to establish e- to ST 6049 at sector 30-5.
